A hard-nosed star reporter learns who her real friends are -- and gets in way over her head -- investigating a murder in this twisty thriller. Perfect Stranger stars Halle Berry as Rowena, a prominent New York journalist who writes using a pseudonym to entrap some of the tri-state area's most corrupt individuals, using a network of informants, acquaintances, and digital gadgets. When her latest exposé is buried at the behest of her paper's corporate backers, she walks off the job and into a personal quagmire. Her childhood friend Grace (Nicki Aycox) is murdered when she threatens to reveal she's been sleeping with married advertising mogul Harrison Hill (Bruce Wills). With the help of her loyal techie friend Miles (Giovanni Ribisi), she goes undercover -- and online -- to find the smoking gun that will indict Hill. But Rowena soon finds herself caught in a web of manipulation, deceit, and false truths.
